One Night in Karazhan - A Hearthstone Adventure

One Night in Karazhan is Hearthstone's Fourth Adventure! Set in the Tower of Karazhan, the magnificent Medivh is throwing a marvelous groovy party and guess what? We're all invited! There's only one problem though.. Medivh has gone missing.

Karazhan will be released on August 11th. This adventure was released during the Year of the Kraken.

I have been looking everywhere for a release schedule for the wings. Does Blizzard not want to put it in writing or what? I would think it would be Midnight on Thursday of each week, but I guess not. I'm pretty sure the initial wing was available at Midnight.

My guess is that they don't announce the exact time to limit the traffic explosion as soon as a new wing hits. AFAIK or remember, they have done this alot in the past with adventures and expansions. They also didn't announce the time of Tavern Brawls, when they first came out. They always come out the same time (Tavern Brawls) but the hype towards the first one was quite big.
